As I'm quite geeky, I tend to read the ingredients and checks exactly what they are.
This stuff by Aura Cacia is basically salt, baking soda, and essential oil. All of which you can get quite easily in your kitchen and add 1-2 drops of listed essential oil.
Absolutely no health benefits, and absorbing SALT increases blood pressure.
Don't be fooled by its package and those 5 star reviews.
Read the ingredients yourself.
